3view Ltd MAC Prefix: Vendor Identified, Device Unknown
Summary
- // what this is
- 3view is registered to MAC prefix
70:E1:39in the IEEE OUI database. When a device's MAC address begins with70:E1:39, that block was registered by 3view — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies an IEEE registry assignment. For this 24-bit prefix, the Group and Local bits are both 0 and fixed for an exact match; changing either bit produces a different prefix. There are 16,777,216 possible 24-bit suffix values, not an observed device or shipment count. RFC 7042 provides MAC prefix and bit interpretation guidance.
About this vendor.
A MAC address beginning with 70:E1:39 is listed under the IEEE MA-L assignment for 3view Ltd; the record does not identify a device category. A prefix match supports the registry assignment only, not a specific product, operating system, current legal identity, or security status.
70:E1:39 is a 24-bit prefix, leaving 24 bits (16,777,216 possible suffix values) in a 48-bit address. That is a count of possible suffixes, not a device or shipment count. Because this exact prefix has Group bit 0 and Local bit 0, matching addresses have those bits fixed. Changing either bit changes the prefix and is outside this exact match. RFC 7042 explains the significance of these MAC address bits and prefix structures.
The IEEE record lists an assignment to 3view Ltd. Products, industry, and website: Unknown.
